Adding an SQL Query action to a test

The SQL Query action queries the selected database to verify that its contents match the selected values. As you add this action, you can validate or store the query results.

Before you begin

Ensure that the database resource is properly configured in the Architecture School perspective. For more information about configuring a database resource, see Database resources, connections, and bindings.

You must have a test. For more information about creating tests, see Test Factory. Tests include steps and actions. For more information about test steps and actions, see Test actions.

About this task

Selecting a test

Procedure

In the Rational® Integration Tester Test Factory perspective, double-click the test where the SQL Query action is to be added.
In the Test Editor window, click General > SQL Query.
To edit the action, double-click the SQL Query action.
The SQL Query dialog opens where you can add the SQL SELECT statement.

Adding an SQL SELECT statement

About this task

To return results against the selected database, add an SQL SELECT statement. Data that is returned from the query can be validated once it is retrieved.

Procedure

Select a database resource from the available resources in the project by clicking Browse.
The initial list of databases is derived from the information that is provided in the Architecture School perspective. If the operation that you are creating a test for has a dependency on a database, then that database shows in the list when Obey References is set to Yes. If you want to work with a database where there is no dependency link to the current operation, all databases in the project can be viewed by setting Obey References to No.
Enter a query (that is, a SELECT statement or stored procedure call) in the Query (SELECT) field.
Optional: Click the Is stored procedure? check box if you are entering a stored procedure, and modify the syntax of the query, for example, {call procedure (var, var)}.

Tip: If you are using a stored procedure call, you might want to use the Stored Procedure action instead (see Adding a Stored Procedure action to a test). This action presents the available functions and input and output parameters more clearly.
Optional: Enter the number of rows or records that are to be fetched from the database when the query is run in the test, in the While testing, limit the number of fetched rows to field.

Note: The default value of the rows to be fetched is set to 100 rows. You can enter 0 if you want all the rows to be fetched. When you set a large number of rows to fetch based on the records in the database and the database driver version that is installed, it might take a longer time to fetch the records.
Optional: Click the Retry query until assertion passes check box and set the Interval and Timeout options when you want the test action to repeat the validation attempts. A validation attempt might be needed where database writes are performed by another process that is running asynchronously to Rational® Integration Tester, and if the query runs before the data is committed. The query is tried every [Interval (ms)] until [Timeout (ms)] is reached.
Save the SQL Query action by clicking OK.

Testing an SQL SELECT statement

About this task

Before you run the SQL SELECT statement against a selected database, it might be a good idea to test the SQL SELECT statement.

Procedure

To run the query and retrieve the data without running the test, click Test.
The results of the query are displayed and any returned data is shown in the Preview dialog.
Important: If the query was canceled before it finished, any data that was built before it was canceled is displayed.
The data that is retrieved by running the query now can be reused to validate the data that is returned by the query when it is run as part of a test. To do this, click Overwrite expected result; it is then used to fill in data on the Assert and Store tabs. Otherwise, click OK to return to the SQL Query action without copying any data.

Editing the query results or manually adding data

About this task

If you did not run a test query and save the results, you can add data from the Assert tab or Store tab, by using the icons.

If you ran a test query and saved the results, the column headings (and data) are displayed in the Assert tab and Store tab, and the rows, columns, and cells can be edited and arranged by using these same icons above the data. To see what an icon does, hover over it.

Procedure

Select any row and append a row to it, insert a row after it, or delete the selected row. You can also move the selected row up or down.
Select any column and append a column to it, insert a column after it, or delete the selected column. You can also move the selected column left or right.
To clear all the data, click Clear Expected Results ().

Validating query results

About this task

To change the validation rules for a cell or column, use the Assert tab. Column assertion validates that all cells in a column match the rule for that column. For example, you might want to assert that all cell values for that column match a certain regular expression. Cell assertion validates that a specific cell for that column matches the rule set for that cell. You can use both cell and column validation rules. For example, you might want to assert that all values in the column contain 4 digits and that a specific cell contains the value 1234.

Procedure

Customize the validation options by using options that are described in the following table. If assertions are disabled, assertions can still be created and modified, but they are not used, including the comparison between the number of rows that are expected and the number received.

Important: Cells with no enabled Assert actions are shown in gray. Cells with enabled assert actions are turned on by default. When you edit a cell, by default the validation is an Action Type of Equality and it is turned on. However, when you edit a column, the default validation, Action Type of Equality is turned off. If you want to use the default column validation or change that validation to another action type, you must turn it on.


Option	Definition
Disable cell assertions	To disable cell assertions, click the Disable cell assertions check box. This selection disables any assertion actions that exist in the cells. When this option is selected, column assertions are used.
Disable column assertions	To disable column assertions, click the Disable column assertions check box. This selection disables any assertions that are made on any received value, independent of the cell assertions. When this option is selected, cell assertions are used.
Validate column types	To validate column types, click the Validate column types check box. This selection validates any data types that are made on any received value, independent of the cell types. When this option is selected, column data types are validated.

Customize the validation options further by enabling or disabling cell assertions on a column by column basis. Some examples are shown.

Validate actions are disabled for all cells in GENDER and WEEK_NUMBER and enabled for all cells in the other columns.

By selecting the Field Actions menu on a column, you can see that all cells in that column have an enabled Equality action.

When you click Field Actions > Validate > Equality the validation of all cells in the column are disabled.

If some cells in a column are enabled with the Equality action and other cells are disabled, you see Field Actions > Validate > ? Equality when you select the Field Actions menu.

If some cells in a column are enabled with the different Assert actions, you can see those actions when you select the Field Actions menu.
To edit a cell, select any cell and click Edit Cell () or right-click the cell and select Edit Cell.
When you are editing a cell, the field editor opens. You can then change a cells value or validation options. By default the validation is an Action Type of Equality, and the value is set to whatever value is in the database within that field. For more information about the field editor, see The Field Editor.

By default, all of the data cells are validated against the data that is shown in them. Therefore, when the test is run, the SQL query must return this exact data.
Edit the validation rules for a column. Select any cell within the column and click Edit Column () or right-click the column heading and select Edit Column.
When you are editing a column, the field editor opens. You can then change the validation rules for the column. By default the validation is an Action Type of Equality.
In this example, the check box next to Equality was not selected. Instead, Regex was selected from the Action Type list and enabled by selecting the check box next to Regex. The Expression field contains an expression to validate that the reservation number is in the format A followed by five digits. This validation rule can be checked by using the Document field and clicking Test.
When you edit a cell or column, you can choose other Validate tab options. For more information about each option, see The Field Editor.

By default, all of the data cells are validated against the data that is shown in them. Therefore, when the test is run, the SQL query must return this exact data.

Storing the return value in to a tag

About this task

You can store the values in a tag, either as a list or as a single value. When you edit a column, all the values for that column are stored in the specified tag as a tag list. When you edit a cell, a single value for that cell is stored in the specified tag. For more information about storing data in to a tag, see The Field Editor.

To store the values for a column or the value for a cell in a tag for later use, use the Store tab. For example, you might want to set the value of the tags in the test to the values of each column in the data source.

Important: Starting in 9.2.0.1, you can use the column's Field Actions menu to set the enabled state for the Validate and Store actions of its cells. Note that both classes of actions can be accessed in both the Assert and Store tabs.

Field actions menu for the Store tab

In addition, cells with no enabled Store actions are shown in gray.

Disables store actions

Procedure

To store a value from a selected cell in to a specified tag, click Edit Cell () or right-click the cell and select Edit Cell.
Click the Store tab.
